Detailed Description
The following is further detailed by the specific embodiments:
example one
As shown in fig. 1 and 2, a pipe 1 of a battery pack cooling system, a liquid inlet 2 and a liquid outlet 3 of the pipe 1 are respectively arranged on an end surface of the pipe 1, a reinforcing rib 4 is arranged inside the pipe 1 along the extending direction of the pipe 1, and the reinforcing rib 4 divides a first compartment 5 and a second compartment 6 inside the pipe 1.
One end of the first compartment 5 is communicated with the liquid inlet 2, the other end is communicated with the liquid outlet 3, and liquid at the liquid inlet 2 flows to the liquid outlet 3 through the first compartment 5. A first baffle plate 7 and a second baffle plate 8 are arranged in the second compartment 6; the first baffle 7 plugs one end of the second compartment 6 at the downstream of the liquid inlet 2 of the pipe fitting 1, and the second baffle 8 plugs the other end of the second compartment 6 at the upstream of the liquid outlet 3 of the pipe fitting 1, so that a part of the second compartment 6 between the first baffle 7 and the second baffle 8 forms a closed cavity.
In this embodiment, a first pipe joint 9 and a second pipe joint 10 for connecting the pipe 1 are both installed on the end surface of the pipe 1, the first pipe joint 9 conveys liquid to the liquid inlet 2 of the pipe 1, and the liquid flows into the second pipe joint 10 directly through the first compartment 5 and the liquid outlet 3. The first baffle 7 in the second compartment 6 limits liquid in the first pipe joint 9 to enter the closed cavity, and the second baffle 8 can prevent the liquid in the second pipe joint 10 from flowing back into the closed cavity, so that no liquid flows into the closed cavity, the accumulated liquid in the pipe fitting 1 is reduced, the load of the pipe fitting 1 is small, and the structural strength is high. By adopting the pipe fitting 1 in the embodiment, the requirement of the cooling system on the structural strength can be reduced, and the production cost is reduced.
In this embodiment, to facilitate the installation of the blocking plate into the second compartment 6, the side wall of the second compartment 6 is provided with a first insertion hole 11 opposite to the first stopper; the side wall of the second compartment 6 is open with respect to the second flap 8 to a second receptacle 12. The presence of the first and second insertion holes 11, 12 facilitates the direct insertion of the first and second flaps 7, 8 from the side of the tube member 1
In the second compartment 6, the second compartment 6 between the first baffle 7 and the second baffle 8 forms a closed cavity, so that the operation is convenient.
In this embodiment, the first blocking piece 7 and the second blocking piece 8 are spaced from both end faces of the pipe fitting 1, so that the interference between the first blocking piece 7 and the pipe fitting and the interference between the second blocking piece 8 and the pipe fitting are avoided. In some embodiments, as shown in fig. 3, the first blocking piece 7 and the second blocking piece 8 can be directly installed on the end surface of the pipe member 1.
In the present embodiment, the pipe 1 is a square pipe, and the reinforcing ribs 4 in the pipe 1 form a cross section of the pipe 1 into a "herringbone" structure. The provision of the reinforcing ribs 4 not only enhances the structural strength of the pipe 1, but also enables the first compartment 5 and the second compartment 6 to be formed inside the pipe 1.
In this embodiment, the cross sections of the first compartment 5 and the second compartment 6 are both rectangular, and strip-shaped through holes are formed in the other three side walls of the second compartment 6 except the reinforcing ribs 4, in positions corresponding to the first baffle 7 and the second baffle 8. Three strip-shaped through holes corresponding to the first baffle plate 7 are communicated to form a first insertion hole 11, and three strip-shaped through holes corresponding to the second baffle plate 8 are communicated to form a second insertion hole 12. The first flap 7 and the second flap 8 are inserted into the second compartment 6 from the side of the second compartment 6 and abut against the reinforcing bar 4.
The pipe 1 in this embodiment is not limited to the square pipe described above, and a common pipe 1 such as a circular pipe or a polygonal pipe may be used.
Example two
In this embodiment, the pipe member 1 is provided with a reinforcing rib 4 inside in the direction in which the pipe member 1 extends, the reinforcing rib 4 separating a first compartment 5 and a second compartment 6 inside the pipe member 1. As shown in fig. 4, the difference from the first embodiment is that the liquid inlet 2 and the liquid outlet 3 are both opened on the side wall of the pipe member 1, and the liquid inlet 2 and the liquid outlet 3 are both notched on the side walls of the first compartment 5 and the second compartment 6.
In this embodiment, as shown in fig. 5, the inlet 2 and the outlet 3 are in communication via a first compartment 5 for liquid to flow from the inlet 2 to the outlet 3. A first baffle 7 is provided in the second compartment 6 downstream of the liquid inlet 2 and a second baffle 8 is provided in the second compartment 6 upstream of the liquid outlet 3, such that the second compartment 6 forms a closed cavity in part between the first baffle 7 and the second baffle 8.
In this embodiment, in order to facilitate the installation of the blocking sheet, a first insertion hole 11 and a second insertion hole 12 are formed in the side wall of the second compartment 6, the first insertion hole 11 allows the first blocking sheet 7 to be inserted into the second compartment 6, and the second insertion hole 12 allows the second blocking sheet 8 to be inserted into the second compartment 6.
In this embodiment, a first pipe connector 9 and a second pipe connector 10 for connecting the pipe 1 are both mounted on the side walls of the pipe 1, the first pipe connector 9 delivering liquid to the liquid inlet 2 of the pipe 1, the liquid entering the first compartment 5 and the second compartment 6 through the indentations made on the first compartment 5 and the second compartment 6. The cooling liquid in the first compartment 5 flows directly through the outlet 3 into the second pipe connection 10 and the first flap in the second compartment 6 prevents the liquid in the first pipe connection 9 from flowing into the closed cavity. The liquid in the second pipe joint 10 will flow back into the second compartment 6 through the gap, and the second baffle 8 in the second compartment 6 prevents the liquid in the second pipe joint 10 from flowing into the closed cavity, so as to avoid the liquid from being accumulated in the closed cavity.
The present disclosure is not limited to only the description and the embodiments, and therefore, it will be apparent to those skilled in the art that additional advantages and modifications can be easily achieved by providing the pipe member 1 with the liquid inlet port 2 and the liquid outlet port 3 on the side wall, or by providing the pipe member 1 with the liquid inlet port 2 and the liquid outlet port 3 on the side wall as shown in fig. 6, and the first blocking piece 7 and the second blocking piece 8 in the present embodiment are selected for the pipe member 1 with the liquid inlet port 3 on the end surface. The disclosure is therefore not to be limited to the specific details, representative apparatus, and illustrative examples shown and described herein, without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
